Why is the joule, the SI unit of energy, also the appropriate unit for measuring heat?

Solution
Unit for heat:
A kind of energy known as heat is defined as flowing from a body with a higher temperature to one with a relatively low temperature. It appears as vibrations at the atomic level and is typically referred to as thermal energy.
Heat energy is also a form of energy and its unit is also Joule. All forms of energy are measured in Joules.
One Joule is defined as the amount of energy exerted or work done when a force of one newton is applied to cause the displacement of one meter.
Also, the unit of heat is calorie (C) but calorie is not the SI unit of heat.
